3rd century AD, (Musée du Louvre, Paris). Archeologist Janet Stephens recreates a hairstyle like this on her ytb channel. This hairdo would be done by an ornatrix, a specially skilled slave. This was one of the few "better careers" female slaves could pursue at a relatively young age. Training to be an ornatrix starts in childhood and in teenagehood a girl already could work in this field.
